Adobe AD0-E722 Adobe Commerce Architect Master Exam Practice Test
Question 1
An Adobe Commerce Architect is working on a scanner that will pull prices from multiple external product feeds. The Architect has a list of vendors and decides to create new config file marketplace.feeds.xml.
Which three steps can the Architect take to ensure validation of the configuration files with unique validation rules for the individual and merged files? (Choose three.)
Answer : B, C, E
The Architect can take the following steps to ensure validation of the configuration files with unique validation rules for the individual and merged files:
Create validation rules in marketplace.schema.xsd. This file defines the structure and constraints of the XML elements and attributes for the marketplace.feeds.xml configuration file. The Architect can use this file to specify the required and optional elements, data types, values, and patterns for the configuration file.
Provide schema to validate a merged file. This schema is used to validate the final configuration file that is generated after merging all the individual configuration files from different modules. The Architect can use this schema to check the consistency and completeness of the merged configuration file.
Provide schema to validate an individual file. This schema is used to validate each individual configuration file from each module before merging them. The Architect can use this schema to check the syntax and validity of each configuration file.
Question 2
An Adobe Commerce Architect needs to customize the workflow of a monthly installments payment extension. The extension is from a partner who is contracted with the default website Payment Service Provider (PSP), which has its own legacy extension (a module using deprecated payment method).
The installment payment partner manages only initializing a payment, and then hands the capture to be executed by the PSP Once the amount is successfully captured, the PSP notifies the website through a webhook. The goal of the webhook is only to create an "invoice" and save the "capture information" to be used later for refund requests through the PSP itself.
The Architect needs the most simple solution to capture the requested behavior.
Which solution should the Architect implement?
Answer : C
Question 3
A merchant is using a unified website that supports native Adobe Commerce B2B and B2C with a single store view.
The merchant's objective is to display the B2B account features, such as negotiable quotes and credit limits, in the header of the site on every page for logged-in users who belong to a B2B company account.
Each B2B company possesses its unique shared catalog and customer group, while numerous customer groups for non-B2B customers undergo changes. The merchant insists that this association should not be linked to customer groups.
Which two solutions should the Architect recommend for consideration, taking into account public data and caching? (Choose two.)
Answer : B, D
Question 4
A client has multiple warehouses where orders can be fulfilled. The cost of shipping goods from each warehouse varies by day, due to the number of workers available. The Architect needs to make sure that when an order is shipped, it is shipped from the lowest cost warehouse that is open.
How should this functionality be implemented?
Answer : B
According to the Adobe Commerce documentation, the Source Selection Interface is the main interface for implementing custom source selection algorithms. The interface defines a method called execute(), which takes a list of items to be shipped and a stock ID as parameters, and returns a SourceSelectionResultInterface object, which contains the recommended sources and quantities for each item. The Architect can create a new class that implements this interface and provides the logic for finding the lowest-cost warehouse that is open for each item. The Architect can then register the new class as an option for the source selection algorithm in the di.xml file of the custom module.
Question 5
An Adobe Commerce Architect creates a stopword for the Italian locale named stopwordsjtJT.csv and changes the stopword directory to the following:
What is the correct approach to change the stopwords directory inside the custom module?
Answer : A
According to the Adobe Commerce documentation, the correct approach to change the stopwords directory inside a custom module is to use dependency injection to override the default values of the stopwordsDirectory and stopwordsModule parameters of the \Magento\Elasticsearch\SearchAdapter\Query\Preprocessor\Stopwords class. The stopwordsDirectory parameter specifies the relative path of the stopwords directory from the module directory, while the stopwordsModule parameter specifies the name of the module that contains the stopwords directory. By adding these parameters to the di.xml file of the custom module, the Architect can change the location of the stopwords files without modifying the core code or database.
Question 6
An Adobe Commerce Architect is creating a new GraphQL API mutation to alter the process of adding configurable products to the cart. The mutation accepts configurable product ID. If the given product has only one variant, then the mutation should add this variant to the cart and return not nullable Cart type. If the configurable product has more variants, then the mutation should return not nullable Conf igurableProduct type.
The mutation declaration looks as follows:
How should the Adobe Commerce Architect declare output of this mutation?
A)
B)
C)
Answer : B
According to the Adobe Commerce documentation, the output of a GraphQL mutation is declared by specifying the type of the data returned by the mutation. The type can be either a scalar type (such as String, Int, Boolean, etc.), an object type (such as Cart, Product, Customer, etc.), or a union type (such as SearchResult, which can be either Product or Category). A union type is used when the mutation can return more than one possible type of data, depending on the input or the logic of the mutation. In this case, the mutation can return either a Cart type or a ConfigurableProduct type, depending on the number of variants of the configurable product. Therefore, the output of the mutation should be declared as a union type that includes both Cart and ConfigurableProduct types. Option B is the only option that correctly declares a union type using the pipe symbol (|) to separate the possible types. Option A and Option C are incorrect because they use brackets ([ ]) and curly braces ({ }), which are used for declaring list types and input object types, respectively.
Question 7
A company wants to build an Adobe Commerce website to sell their products to customers in their country. The taxes in their country are highly complex and require customization to Adobe Commerce. An Architect is trying to solve this problem by creating a custom tax calculator that will handle the calculation of taxes for all orders in Adobe Commerce.
Following best practices, how should the Architect add the taxes for all orders?
Answer : C
According to the Adobe Commerce documentation, the best way to add a custom tax calculation to all orders is to declare a new total collector in the ''etc/sales.xml'' file of a custom module. This way, the custom tax logic can be implemented in a separate class that extends the \Magento\Quote\Model\Quote\Address\Total\AbstractTotal class and overrides the collect() and fetch() methods. The collect() method is responsible for calculating the tax amount and adding it to the quote address, while the fetch() method is responsible for displaying the tax amount in the cart and checkout pages. The new total collector can be assigned to any area of the order totals, such as before or after the subtotal, shipping, or grand total.
